I am having wifi issues with my S10+ after One ui2.1 update.
The wifi speed on the device never reaches full speed and keeps fluctuating.
I have checked the wifi speed on my pc and galaxy tab s4 and other phones as well and I am getting full speed there.
There was no such issue before the one ui 2.1 update.

Does anyone have the same problem with s10 plus..???
